Hello!

i figured out how to save the instance of my model to XML (with correct encoding)

but how can i add the XSD to my XML file?
i have the XSD in a seperate file and want to either link the xsd in the xml.

i tried:

URI xmlUri = URI.createFileURI(new File("xml/model.xml").getAbsolutePath());
URI xsdUri = URI.createFileURI(new File("xml/model.xsd").getAbsolutePath());
System.out.println("xml: " + xmlUri);
System.out.println("xsd: " + xsdUri.toString());
Resource resource = resourceSet.createResource(xmlUri);
resource.getContents().add(instanceModel); // adding my instances to the resource
Map<String, String> options = new HashMap<String, String>();
options.put(XMLResource.OPTION_ENCODING, "UTF-8"); // set encoding to utf-8
// options.put(XMLResource.OPTION_SCHEMA_LOCATION, xsdUri.toString()); // not working
options.put(XMLResource.OPTION_SCHEMA_LOCATION_IMPLEMENTATION, ServerPackage.eINSTANCE.getNsURI()); // not working
// save to file
resource.save(options);
// print to console
resource.save(System.out, options);

how can i put those things together? (note that the xsd file is located at this place always, its not generated when you save the xml... -> later this xsd _could_ be located on a webserver)
